IMPROVEMENT IN CLOSING THE MOUTHS 0f BOTTLES, 61C., AIR-TIGHT.

Speeiticaton forming partof Letters Patent No. 11,513, dateclAugust 15, 1854.

To @ZL wiz/0m, it may concern.-

Beit known that` I, ROBERT ARTHUR, of the city and county of Tashingtoin in the District of Columbia, haveinveuted anewand useful Improvement in Bottles, Jars, Pitchers, or other Similar TVessels, closed in a peculiar manner, for pharmaceutical and other purposes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form part of this specification.

M v invention consists in making an annular groove or receptacle near the mouth of the vessel. Vas shown in Figs. l and 2', for the purpose of containing some yielding medium, into which the lower part or edge of a cap or stopper passes when the bottle is closed, thus completely cutting off its content-s from contact with the external atmosphere. By this contrivance the evaporation of very volatile liqnids-such as ethers,chloroform, Std-and the deliquescence of certain salts may be prevented and other useful objects accomplished, while the bottle can'be conveniently opened and closed. An important feature of the groove is its form, it being so' curved that,

' while it contains a quantity of fluid sufficient for the purpose intended, the vessel may be entirely inverted and its contents poured out without spillingthe fluid deposited in the groovc, for the purpose of rendering the joint of 4the stopper air-tight. `The groove or. receptacle may be formed of the same material of which the bottle is made, or it may be made of any other material and attached to the bottle after it is otherwise completed'. The neck of the vessel may also 4be, enlarged and the groove made of a proportionate size, so that the vessel will assume the proportions of a j ar; or the vessel may be-made of any convenient form, as my invention relates to the'mode of closing` only, and'not .to the general configuration or proportions of a vessel.

In the accompanying drawings, a represent-s the body of a bottle; b, the neck, which is surrounded by a fillet, c, to form a groove around the neck of the bottle. This groeve is narrow at the bottom at, wide at the top,

and the upper edge' of thc fillet is curved in' ward, as represented, to form an inverted `cha-nnel,.o, into which anyliquid within the groove retreats when the bottle is inverted, and returns again to the bottom ofthe groove when the bottle is placed in an upright posi tion with its bottom downward. An annular space is left between the upper edge 'ofthe iillet c and the side of the neck b sufficiently wide to admit the stopper or cap d. Thelower edge, e, of the rim of the cap enters the narrowest part of the groove,` so that a comparatively small quantitv of liquid Vwill ll the groove to half its height and immerse 4the lower edge of the rim to a considerable depth.

Among other'liquids which I have used in the groove and found suitable for various purposes, I will mention mercury, which may be used when the vessel is to contain such liquids as would either absorb water, glycerine, 815e., or be absorbed or injured by them. I will also mention water, glycerine, molasses, or honey, either of which may be used with advantage when the contents of the vessel will not be effected by them. I do not, however, coniine myself to theuse of these liquids,- as there are many others 'that may be employed 4with equal advantage.

I donot claim the invention of any method of rendering vessels air-tight by the aid of caps or Stoppers, screwed or cemented in place, but only the vessel so contrived as to be made tight by means of a groove or receptacle containing a yielding medium which is to be penetrated bythe cap or cover, with the receptacle so contrived that the bottle maybe in verted to pour out its contents without spilling the liquid or yielding medium from the groove or receptacle, as herein set forth.

In testimony whereof I have hereunto subscribed my name.

ROBERT ARTHUR.
